What is the role of the ureters in the urinary system?

The role of the ureters in the urinary system is to direct urine from the kidneys to the urinary bladder. The ureters are muscular tubes that transport urine through peristaltic movements, which are wave-like contractions that help propel the urine downward. This function is crucial for the efficient movement of urine, ensuring that it reaches the bladder where it can be stored until excretion.

The ureters do not serve as a reservoir for urine; that function is fulfilled by the urinary bladder itself. Additionally, while the kidneys filter waste products from the blood, the ureters do not have any filtering capability; their role is specifically related to the transportation of urine. Finally, the control of urine release is managed by the sphincters in the bladder and not by the ureters. Overall, the primary and correct function of the ureters is to serve as the conduits that carry urine from the kidneys to the bladder for storage.
